Automating Xray Node Deployment with 3xui-fast-install

Ultimate 1-Minute Xray/3x-ui Setup: VLESS, Hysteria2, Caddy Self-Steal & Smart Outbounds in One Script

Dmitry has released 3xui-fast-install, an automated deployment script for Xray gateways. It reduces the configuration time for a production-ready node from one hour to 60 seconds.

Why This Matters

Manual setup of circumvention gateways typically involves tedious, error-prone steps including Docker installation, TLS certificate generation, and complex routing table tweaks. By automating the integration of Caddy for TLS termination and configuring smart outbounds like Cloudflare WARP and Tor, the script eliminates common misconfigurations that lead to active probing detection or IP leakage.

Key Insights

• The system utilizes VLESS + Reality on port 443 to mimic legitimate TLS handshakes to evade detection.
• High-performance UDP transport is achieved via Hysteria 2 on port 63000, optimized for unstable mobile networks.
• Server-side routing implements ‘blocked’ rules for adblock/malware and routes domestic traffic through Cloudflare WARP to mask the VPS IP address.

Working Examples

One-command deployment script for Ubuntu/Debian VPS.

bash <(curl -sL https://raw.githubusercontent.com/AppsGanin/3xui-fast-install/main/install.sh)

Practical Applications

• Rapid VPS Cycling: Engineers can migrate nodes between providers quickly without manual reconfiguration of firewalls (UFW) or congestion control (BBR).
• Privacy Routing: Using Tor outbounds for .onion addresses prevents direct VPS exposure; failure to implement this often results in leaking server metadata.
